Which of the following is an assumption on which the argument depends?
A. The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.
B. There is no single region to which all the species depicted in the Sepphoris mosaics are native.
C. No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.
D. All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.
E. There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar. 作者: daisydaisytian 时间: 2011-8-5 10:48

Conclusion: the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire
Premise: 1) Excavations of Roman city of Sepphoris uncovered things that didnt live in Sepphoris 2) same things were found in other Roman city
Assumption?
if you negate E, the conclusion falls apart. because if E happened, it can also perfectly explain why these "Uncovered things" were uncovered in different cities.
C) it is irrelevant. ==> all "things" found in S can be found in other cities. this is more like a restatement of the premise to me.
